It seems Python provides a higher level solution compared with VBS. 
Python presumably also has to do those Opens and Sends, but they are 
hidden away inside urllib.urlretrieve.

You can do the same with VB just by wrapping up these lines in a 
subroutine. As you would if this had to be executed in a dozen different 
places for example. Then you could just write:

getfile("http://econpy.pythonanywhere.com/ex/001.html", "D:/file.html")

in VBS too. (The forward slash in the file name ought to work.)

(I don't know VBS; I assume it does /have/ subroutines? What I haven't 
factored in here is error handling which might yet require more coding 
in VBS compared with Python)
